Although my DD is 6, we had experience with the 3-5 as my neice is 4. We went on the 5/1 Eastern. We checked the kids in on Saturday and granted it was a bit hectic to me. The counsellors didn't seem at all fazed, so I guess to them it was not. However, by that evening all had settled down. We had not a bit of trouble. As far as people saying they did not get paged, I do not understand that at all because I got paged for my DD. When I got there she was fine so I was going to leave her, but the CM told me that since they promised the kids that their parents would come as soon as they paged I needed to go talk to her. As it turns out she was fine, just wanted to page me! LOL
My neice is 4 and a bit of a handful. She had a great time, but they paged us alot for her. She wanted to stay, she wanted to leave, she wanted to stay.....
That is my personal experience.
